I'm using the 2.6.25 kernel from debian sid, it works fine. I think ubuntu can use debian packages as well. To solve the screen problem, you need the following command line: video=efifb agp=off If you're interested, you can also try amd64 kernel. You can use it on 686 linux directly, no need to install a full amd64 system. >>>>> - appleloader always tells me "Model : Core Duo/Solo" and nothing else >>>>> (no >>>>> matter whether I give it a parameter or not).

Are you sure you type the command exactly as it is ? appleloader HD boot You can also try my compiled version, see if it works. -- Bean _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
